the difference is we have stopped trying because after everything we've been through we have had to face and accept that children don't feature in our future. That's very different from stop trying as in still hoping and expecting to conceive. When I say a weight is lifted, that weight is my desperate longing for a baby and my acceptance that we will be childless
I've been there and done that so I feel for you, it's a hard thing to accept. In our case we actively pursued and tried everything for 15 years. The day the consultant said "go home there's nothing more we can do for you" we finally had to accept it and it was both a relief and a heartbreak. Those 15 years were the longest and hardest of my life. The grieving process was tough too and, like you, it took about 3 yrs to finally feel able to plan our childless future. During those 15 years my 5 sisters had a total of 13 children between them, I was the only one who couldn't get pregnant.
InFertility isn't the domain of the overweight, unfit, smokers. We sat in the assisted conception clinic month after month with fat, thin, fit, unfit, smoking, non smoking, poor, and wealthy people. There is no rhyme or reason for some people's fertility. And all the platitudes in the world can't change that however well meaning they are.
I worked in a social services nursery. Some people just don't deserve children and how unfair is it that people who don't care enough can get pregnant but not me. How dare they pop out children one after the other with no thought. These were thoughts I had daily, but I tried to remember it wasn't their fault I couldn't get pregnant, and the people who trotted out the platitudes were just trying to think of something positive to say in a difficult situation. I never wanted to adopt, or use a donor. I just wanted my own baby.
But then I became "that person". The one who, after years of heartache and treatments fell pregnant completely out of the blue. I was 39 and DH 47. We were devastated. All our new plans completely out of the window, we were too old, and a hundred other reasons that it was a bad thing not good.
Life is a curveball that's for sure. 2 years later I was pregnant again. We are the oldest parents on the block. Our boys are now 17 & 20.
So I know both sides. I try not to tell people "it might still happen", I know how patronising and heartbreaking those words can be. But at the same time, here I am.
I hope it works out for you, and for all others in the same boat. It won't for many, but for some it will.
